Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a pipe transfer device for transferring short pipes made of metal such as aluminum that have been conveyed by a conveyor to another conveyor.

Conventional technology Short metal pipes such as aluminum pipes that require high precision in diameter, roundness, wall thickness, straightness, etc. are often made into long drawn pipes by drawing the extruded pipes. It is often manufactured by straightening a straight pipe, cutting it into predetermined lengths, cleaning it to remove chips, and then processing the end face of the pipe.

In the manufacturing of metal tubes as described above, the cleaning process performed between the cutting process and the end face processing process is, for example, equipped with a support pin that can be inserted into the end of the drawn tube in order to automate the cleaning process and improve efficiency. One possible method is to use a conveyor in which a large number of pipes are arranged at predetermined intervals in the length direction, and to transport the cut pipes with the cut pipes inserted into each support pin while passing them through a washing machine. When adopting such a method, in light of the conventional state of the art, the operator must use his/her hands wearing special gloves to cut the short tube conveyed from the cutting device by a conveyor consisting of a pair of endless chains on the left and right sides. It requires manual work to take it out from the conveyor and insert it into the support pin of the above-mentioned plug-in type conveyor.

Problems to be Solved by the Invention However, manual removal and insertion as described above leads to inefficiency of work and makes mass production of drawn pipes difficult.

Furthermore, even when manual work is performed by a skilled worker with great care, there is a concern that the outer surface of the drawn tube may be scratched by sliding contact with gloves.

Thus, in particular, metal tubes are used in the manufacture of photoconductor drum substrates supporting photoconductive layers such as selenium or organic photoconductors, for example in photoconductor drums of electronic copiers, laser printers, etc. In the case of pipes for which surface quality is strictly required, there is also the problem that the above-mentioned scratches can be fatal, leading to a decrease in manufacturing yield.

The present invention solves the above-mentioned conventional problems and includes a first conveyor that conveys a pipe while supporting the lower surface of its outer periphery, and a support that can be inserted into one end of the pipe. The pipe on the first conveyor can be efficiently and automatically transferred to the second conveyor without causing any damage between the pipe and the second conveyor which is equipped with a pin and supports and conveys the pipe with the support pin. The purpose of the present invention is to provide a pipe transfer device.

Means for Solving the Problems The above objective is to provide a first conveyor for conveying a pipe while supporting its lower surface, and a support pin that can be inserted into one end of the pipe. A pipe transfer device that is disposed between a second conveyor and a second conveyor to transfer a pipe conveyed by the first conveyor to the second conveyor, the pipe having a support pin that can be inserted into the end of the pipe at the tip. and a holding body that holds the actuator so that it can move forward and backward and is rotatably supported around an axis perpendicular to the direction of movement of the actuator, the actuator facing the first conveyor. In this state, after the actuating body is moved forward to insert the support pin of the actuating body into the pipe on the conveyor, the actuating body is held in such a manner that the actuating body passes through the upper side so as to face the second conveyor. The conveyor is rotated, and then the actuator is moved forward to insert the bearing pin of the second conveyor into the pipe supported by the bearing pin of the actuator, and then the bearing pin of the actuator is pulled out from the end of the pipe. This is achieved by a pipe transfer device characterized in that the actuating body is retracted and then the holding body is controlled to rotate so as to bring the actuating body to face the first conveyor.

Operation In the transfer device described above, when the pipe is transported to a predetermined position by the first conveyor, the actuating body moves forward and the support pin is inserted into the pipe.

Then, the holding body is rotated in such a manner that the operating body supports the pipe and passes through the upper side, the operating body faces the second conveyor, and the pipe is arranged on the axis of the support pin of the second conveyor. .

Next, the actuator is moved forward, and the support pin of the second conveyor is inserted into the pipe supported by the support pin of the actuator.

Subsequently, the operating body is retracted, its bearing pin is extracted from the end of the pipe, and the pipe is supported on the bearing pin of the second conveyor. Then, the second conveyor starts driving,
This pipe is transported to, for example, a washing machine. Further, in the transfer device, the holding body is rotated so that the operating body faces the first conveyor, and the same operation as described above is repeated.
